Hi all,

Well after missing out on a T293 lsd diff today, i decided to have a wander down at the local. Armed with my trusty tape measure and a pack of smokes, i now have some info for all you wannabes.

T series diff is used to describe a differental which has a 6.7" housing and a 10 bolt carrier. These housings can be found on:

RA40
RA60
T18 (TE72)
TA22/23 (maybe 28's aswell, however i havent found one to look under as yet.)
Note - some TA's have a D housing which is 6.62"

And of course theres the JDM AE86 with discs.

*Edit* forgot to add that JDM can come with drum brakes http://www.ae86drivingclub.com.au/forums/emoticons/rolleyes.gif

Now while theyre all essentally the same thing, many vary in track. The RA series will give ~15mm more on each end while TA's are smaller. (not 100% as i could get under proper like)

T18's will be a dirrect bolt in affair whereares the celica ones will require a longer panhard rod. If you do get an RA series one, it might be worth while to scab the gearbox aswell because you will NEED the rear half of a T18 tailshaft, or custom. For me, id take the diff/tailshaft/W5x and have a doodle to make it fit rather then shopping around for a T18 which i would have taken the diff outta anyway...

RA40/60, TA22's and T18's all use Zenki (early 23 spline) axles. This makes it easy to obtain LSD's for HOWEVER because they are drum brake rears the axels are slightly longer. If you do get a T series rear with drums and souce an LSD, just shave the ends of the axles a lil and it will all be fine. This approach i find is a heap better than scouring high and low for disc brake axles when the finally do snap! Lets face it.. there are plenty more drum rears in this world then JDM disc's. Probably cheaper too.

How to identify a diff:

When searching the wreckers, you will find the diff code on the vehicle id code. T292 is open center by the way.

ADM S series have an 8 bolt carrier housing while KE/AE7x borg warners have an 8 bolt inspection plate.


Opinions/Corrections are welcome. Feel free to ask questions too http://www.ae86drivingclub.com.au/forums/emoticons/tongue.gif

Info has been collected by using search and my own observations. Facts will be available next weekend when i pick up an RA40 diff/tailshaft/W50 gearbox.

How much longer does the panhard rod have to be with the RA series diff? Is an aftermarket adjustable one for ae86 out of the question?

Great article thanks!

biggo
25th March 2006, 08:19 PM
Panhard rod needs to be a few cm apparently. Go ghetto style and cut it, slip a ring around it and weld it togther and your fine...or you could just buy an AE86 adjustable of AJPS for $125 http://www.ae86drivingclub.com.au/forums/emoticons/tongue.gif

I should add that im not 100% on the RA40/60 ones. I was told long ago that something was different probably the spring seats or the trailing arm mounts. Can really recall tho BUT I find out next weekend http://www.ae86drivingclub.com.au/forums/emoticons/biggrin.gif

An RA45GT is 14mm wider and is a F series diff but the mounts are totally wrong

biggo
25th March 2006, 08:35 PM
Yes

Sprinter trd is correct. Dont bother with RA45/65 as the came with F series irs rears.

If someone finds a F303 solid diff - let Nick know http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

Solid axle not irs...

SprinterTRD

The IRS crown wheel & pinion fit into the solid housing. The cw carrier bearings are the same diameter but a little wider.

I have done this many times. Also the IRS LSD fit into the solid housing.

XT/RT 14x Corona's use borgwarner diffs.

27th March 2006, 09:57 AM
so will an RA40 or RA60 diff fit straight in with not too much screwing around? becuase the +15mm on each end means you dont have to run illegal spacers to fill the guards!

This stuff is gold, thx I'll save myself 2k without the JDM diff.

slydar
27th March 2006, 11:37 AM
i am almost certain youre leading people astray with the RA type diff being bolt in.

the spacing of the pick ups will allmost certaintly be differant. not to mention the spring seats.

try it and post it here. once youve worked out that it will definately/def' not fit ill edit it all so the thread only contains good information.

at this point people i would only treat this information as heresay.

Matt-AE86
27th March 2006, 01:32 PM
I can tell you now RA60 rear end isnt a simple bolt in.

From what I know these things are different and need modifying
- Upper Laterl Rod Brackets need to come in 15mm each side.
- Spring seats are different

I have one waiting to go into my ae86, but cant be stuffed modifying it all atm. I will be using a T18 rear bit of the tailshaft.

biggo
27th March 2006, 03:42 PM
Thanks for the heads up guys.

I will be getting an RA40 diff on the weekend (i assume its the same as a RA60) which i hope will comfire what Matt AE86 is saying.

The way i see it is, if i was bothered to weld my sway bar mounts onto an early T18 diff, i might aswell chop the upper lateral arm mounts and move them on an RA40/60 T diff. AFAIK spring seats mean SFA if the springs are still held captive.

Its also a bonus that the axles will be plentiful to scab and mod to fit!

Other than that, I'll update it soon http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

how much do you have to shave off of the axles?

biggo
30th March 2006, 10:46 AM
Not much but enough to fit the LSD in.

Methinks its the same amount as the extra track that you receive

Time will tell however......

3rd April 2006, 10:08 PM
I put a RA60 diff in my KE70 and they bolt straight in accept for the panard bar and coz mines lowered 3-4"
i had to get an adjustable one made anyway, and about the length, theres about 5-10mm difference between the T-18 and the RA60 diff which is why you have to shave the celica axles down to fit them in the T18 diff. The only other difference is that one mounting stud is longer on the celica center. I know this to be true coz my mate has a T-18 diff in his 86 and we compared the 2 http://www.ae86drivingclub.com.au/forums/emoticons/cool.gif

mikes86
3rd April 2006, 10:47 PM
Had a good look at my mates ke with one in it. The upper lat bars are not exacly straight, but would that much of a difference? They bolt in and only need to move 15mm..... Anyone heard of brackets cracking or anything because of it?

Great info fellas! Keep it coming.

sr_rolla - sounds like your info is spot on, thanks for sharing.

mikes86 - I really dont think it will matter that much weather or not the trailing arms are perfectly straight assuming your still using the stock rubber bushes.

Nah, its fine with poly bushes, the only problem I had was that i overtightened the bolts on the diff and pulled the center of the diff mounts in http://www.ae86drivingclub.com.au/forums/emoticons/rolleyes.gif

other than that the bolt holes on the diff mounts are bigger than the T-18 one, they take a 19mm headed bolt instead of a 17mm like the rolla http://www.ae86drivingclub.com.au/forums/emoticons/2thumbs.gif

so is there any easy swaps or interchangable diff centres that will bolt straight in???

22nd April 2006, 05:09 PM
As per your diff center thread, any t series center will fit any t series housing. Its just a matter of which ratio you wish to use.

That said, put your ra60 diff in and post up your findings here http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

Only OEM and TRD LSD's need axle shortening. Most other aftermarket diffs dont need shortening. I can tell you for sure Cusco's dont.

Hi, i have a ra40 diff in my sprinter, bolts in no worries, the top mounts sit 5mm out on each side i think, i got a whiteline adj panhard rod and got them to make it adjust further out, it is 1410mm wide which is 20mm wider than the s series diff by my measurments, this is a cheaper way of getting a t series diff than t18, wreckers seem to want a bit for them these days, dont forget the tail shaft, this cost me $80 which is crazy for a tail shaft. my 2c

has anybody used a TA23 4.3 ratio centre???

slydar
28th April 2006, 01:44 AM
4.3 is extremely rare. 4.1 is common. either will fit.

ra40 diff fitment sounds dodgy. recently bought one for the ratio/axles. bottom arms are indentical spacing, tops are out, flexing the arms bush to make them reach the top mounts is not a good idea, especially on a lowered car. fucked out all bushes probably helps but once your upper control arms are pointing up already + twisted over. its just not good.

also the springs seats are a differant style.. smaller diametre at a glace? didnt bother measuring spacing.

ae86dave
28th April 2006, 02:01 AM
so to end a long story will a ra60/ta23 4.1 ratio centre bolt into a t-18 diff and will the t-18 axles bolt in?.so basically u jus swap centres over.

slydar
28th April 2006, 11:33 AM
yes. just bolt it in. spline and bolt pcd/everything is the same. dont think youll find a t292 ra60 though. more likely ra40. (t292 is the axle code youre looking for, on the build plate)

T= t series obviously. first 2 numbers are the ratio code. 28 = 4.3 29 = 4.1 30 = 3.9 ect. 2 is the nember of pinion gear/lsd or not. 2 = 2 pinion gears, 3 u 2 pinion gears + lsd, 4 = 4 pinion gears, 5 is 4 pinion lsd.

ae86dave

Big T
9th December 2006, 09:05 AM
Is there any reason people dont consider building their own diffs? I find the assurance of having massively fat axles/centre is worth the bit of extra cash used to make it.

9th December 2006, 10:49 AM
how much is it to get a custom diff? ive always had that in mind but always though it would be a rather expensive option?

Big T
9th December 2006, 07:01 PM
They can usually be built for around 1.5k to 2k depending on the setup and how many bearings/seals need to be replaced. I usually make G-series diffs with disk brake setups. Pm me if you want more info.

Seeing as disk brake T-series rear ends go for around1.5-1.6k, having the assurance that it'll NEVER break for an extra few hundred is worth it in my opinion.

9th May 2007, 07:40 AM
yeah but you still have to set preload on the bearings go to tight and they will sieze etc.

Jonny Rochester
9th May 2007, 11:57 AM
Backlash: 0.13 - 0.18mm
pinion preload ~10 kg-cm
sidebearing preload. zero preload plus 1-1/2 notches.

There is a complex procedure to setting up a diff. You had best buy a book. If you want a Toyota manual for the diff, you can use any old Corolla/Trueno/Celica/Sprinter Chassis & Body manual. Otherwise the big thick books you have to buy as an apprentice mechanic will probably cover it.

^ i here what your saying gilly but i take pride in the fact that i have built / done all the modification on my car (execpt for paint) and im not going to stop now.

what is needed to measure the lash and define lash please? I will buy / borrow / steal / whatever it takes

Jonny Rochester
15th May 2007, 03:08 PM
Tools:
Dial indicator
magnetic base stand for indicator
torque wrench and sockets
3 screwdrivers

Back lash is the clearance between the two gears.

Put the dial indicator on a crown wheel tooth, hold the pinion still, and rock the crown wheel. The movement you get can be shown in the dial indicator. Some experienced people can estimate the back lash just by feel.

But backlash is easy to adjust. You also want to put die or paint on the teeth and check the contact pattern. If everything else is right, the contact pattern of the teeth will determine how much the diff will whine and wear out. To adjust it, you need to change the shim under the pinion, not so easy.

BLA57

11th June 2007, 10:34 PM
does anybody have input on what E series diffs are like?
they are larger than a T series centre so id assume they would be pretty strong.
they are not as big and heavy as a G series, as for width, i have too mesure mine up and see how it goes.
just wondering if anybody else has used one thats all.

mikewestphoto
11th June 2007, 10:54 PM
The axles on them are supposed be the same spline/size as a kouki axle. Depending on where you got yours from it could be 1410, 1415 or 1445mm wide mounting face to mounting face.

Kaizen used to do bolt in diffs for a good price, don't know if they still do.

No LSD's for them.

They will hanlde 300rwhp but you might be getting to the higher end of the power handling if you belt the shit out of it(drags). I'm still going to use one for my car until I can find an F-series.

rileymoore05
12th June 2007, 08:35 PM
ah ok. interesting.
havent had a chance to measure mine yet.
no lsd is no problem, i was going to lock it anyway.
apprently some taragos have e series also so i might raid the wrekers and see if i can get some different ratios happening.
should be alright...

mikewestphoto
13th June 2007, 01:32 AM
I'll say your diff is 1410 wide since the cars that they come out of are rare as. If it's a Tarago diff, it'll be 4.1 or 4.3. If you are unlucky (or lucky) you will have a 4.778 from a CM35 Liteace(width unknown).

Everything else is 3.9 except for MX62 which is 3.7.

rileymoore05
13th June 2007, 07:37 AM
yeah, mines from a mx62 cressida and its a 3.7 i belive.
might try and get a tarago 4.1 centre and some spare axles, just in case.

13th June 2007, 11:43 AM
I've searched and got donuts.....

For the t series (mainly t-18), I've heard that the front diff from a
4wd diesel townace van (4.7) fits!!

Can anyone confirm?
Also confirm which exact model of townace?

I might be easy (cheap) way of getting a higher ratio.

EVOSTi
14th June 2007, 10:02 PM
ive got an E series in my car at the moment however the mounts were swapped over for use in a celica so the upper arms are a few mm out. its a decent diff, bigger than T but smaller than F, i also have disc brakes on it with internal drum handbrake so the brakes are tops. been using it for years with the trailing arms the way they are with no problems. also has traction bracket mounts on the bottom.
if anyones considering one i think its a good upgrade as long as you dont want lsd, few ratios available too.
ill prob sell mine in the near future tho.

rileymoore05
18th June 2007, 09:29 AM
found a whole heap of Eseries diffs in taragos at the wreckers on the weekend.
two differnt ratios too what ive already got so might have too go and get em both at some stage, and mabey a set of axles for good measure. - if they are the same length as my mx62 ones.

RA28 / TA22 GT celicas came with LSD's, but you will never, ever find one at a wreckers. The GT's are rare as hens' teeth.

However you should be able to come across a 4.3 ratio easily enough. Most Auto Celicas of the time had them. Toyoland should have one.

Taragos didn't come with T-series as far as I know (and I assume you are after a T-series, no?), but tercels I am not sure about.

Javal
30th July 2007, 11:25 PM
TA22 / RA28 which came from the factory with an automatic transmission.

There is one difference between the centers for the Celicas and the T-18's.

T18 housings have 10 studs. Celica housings have 9 studs and hole for a bolt.

This is because there's a weird extension thing on the celica centres. it's hard to describe.

I THINK you can just remove the stud in question and use the bolt.

Ask chris.

I'm guessing they were on the very early pov pack ones, like, 71 - 72 LT's.

Hey all. This thread has been a huge help to me so i thought i'd give a little back.

I just finished putting an RA40 T series into my ae86 and thought i'd share my findings ( dont know if this has already been said). For anyone looking for a really cheap upgrade to a T series this is definately a goer. RA40 gives about an extra 40mm in total track which means filling the guards without illegal spacers. There is a difference in mounts but it's so small that it wont really effect you if you still have standard rubber bushes ( not to sure about poly bushes).

The top mounts on the RA40 diff are 25mm further apart but as i said before you can just push the upper links out 13mm and works fine. If you use bolts from the S series you shouldnt have a problem. The bolts on the RA40 diff are a bit bigger in diameter which means the bolt holes on the RA40 mounts are a smig bigger too this accomodates for the missalignment. No difference at all on the bottom mounts.

As for brakes, someone said before that the RA40 diff is also a free upgrade ( all be it a drum brake) but from what i could see there is no difference in diameter of the drums. That said they do seem to work better (not a clue why).

The tailshaft from an RA40 can't be used because it is far to long. The standard S series tailshaft can be used with some modification to the centre bearing. By elongating the holes on the bearing mounts you can push the centre bearing closer to the front of the car meaning that the extra 20mm of the T series housing wont bugger up your bearing to quickly. The only problem i can see with doing this is that it may have an adverse effect on the bearings in the gearbox after some time.

There is quite a difference in panhard rod lengths but this can easily be sorted with an adjustable one. I used one from whiteline which works really well. There is no need to get extra length put onto it. I can turn mine atleast another 10 full turns ( if not more) before it comes out of the end. Just make sure that you order a panhard rod for an AE86 not an RA40 celica. The RA40 one from whiteline is 875mm long where as the AE86 one is only 685mm.

Other than that everything else is a straight fit :P

Hope this helps people. Any questions send me a PM (as usual, take this information at your own risk)
Mike :P
